1. Ecological drivers and genetic signatures of evolutionary divergence and local adaptation in pike (Esox lucius)
Abstract : The diversity among species, populations, and individuals in nature is astonishing. Genetic and phenotypic variation constitutes the raw material for evolution. It influences how populations respond to changing environments, and can impact long-term survival of species and ecosystem functioning. READ MORE

2. Population Genetic Methods and Applications to Human Genomes
Abstract : Population Genetics has led to countless numbers of fruitful studies of evolution, due to its abilities for prediction and description of the most important evolutionary processes such as mutation, genetic drift and selection. The field is still growing today, with new methods and models being developed to answer questions of evolutionary relevance and to lift the veil on the past of all life forms. READ MORE

3. Hopeful monsters: The role of hybrids in adaptation : The impact of hybridisation and genetic diversity on adaptation to stressful and novel environments
Abstract : Adaptation to novel environments can only occur if natural selection has the raw material to act upon. But small, endangered populations are often genetically depleted, and the acquisition of beneficial de novo mutations often takes too long when population face quick and extreme environmental change.

4. Genetic adaptation to soil acidification in four grasses
Abstract : Soil acidification has become a source of serious concern in many parts of the world. In southern Sweden, the deposition of acidifying substances, such as nitrogen and sulphur compounds, has decreased the mean pH of forest soils by almost one unit since the 1950s. READ MORE

5. Advances in studying the role of genetic divergence and recombination in adaptation in non-model species
Abstract : Understanding the role of genetic divergence and recombination in adaptation is crucial to understanding the evolutionary potential of species since they can directly affect the levels of genetic variation present within populations or species. Genetic variation in the functional parts of the genome such as exons or regulatory regions is the raw material for evolution, because natural selection can only operate on phenotypic variation already present in the population.
